vop_openclose
VOP_OPEN(9) BSD Kernel Developer's Manual VOP_OPEN(9)
NAME
VOP_OPEN, VOP_CLOSE -- open or close a file
SYNOPSIS
#include <sys/param.h>
#include <sys/vnode.h>
int
VOP_OPEN(struct vnode *vp, int mode, struct ucred *cred, struct thread *td, struct file *fp);
int
VOP_CLOSE(struct vnode *vp, int mode, struct ucred *cred, struct thread *td);
DESCRIPTION
The VOP_OPEN() entry point is called before a file is accessed by a process and the VOP_CLOSE() entry point is called after a file is fin-
ished with by the process.
The arguments are:
vp The vnode of the file.
mode The access mode required by the calling process.
td The thread which is accessing the file.
fp The file being opened.
Pointer to the file fp is useful for file systems which require such information, e.g., fdescfs(5). Use 'NULL' as fp argument to VOP_OPEN()
for in-kernel opens.
The access mode is a set of flags, including FREAD, FWRITE, O_NONBLOCK, O_APPEND.
LOCKS
VOP_OPEN() expects vp to be locked on entry and will leave it locked on return.
VOP_CLOSE() expects at least a reference to be associated with the vnode and does not care whether the vnode is locked or not. The lock and
reference state is left unchanged on return. Note that vn_close expects an unlocked, referenced vnode and will dereference the vnode prior
to returning.
RETURN VALUES
Zero is returned on success, otherwise an error code is returned.
